providing training interventions at various stages of the career to ensure
skilling, re-skilling and up-skilling of employees. For this purpose,
extensive training infrastructure has been created in the form of
Centralised Training Institutes (CTIs), Multi-disciplinary Zonal Training
Institutes (MDZTIs), Multi-disciplinary Divisional Training Institutes
(MDDTIs) and specialised training centres, which conduct induction,
refresher, promotional and technical training programmes at different
stages of service.
Training modules are designed to strengthen employees’ competencies
and equip railway personnel with the skills required for modern,
technology-intensive railway operations. These modules are alsoperiodically updated to incorporate new technologies in railway
operations and maintenance.
Specialised initiatives such as the Centre of Excellence on Kavach at
IRISET, courses on emerging technologies (including Data Science, AI
applications, Big Data Analytics, Block chain, and Cloud Computing, etc.)
in collaboration with C-DAC, and Mission Rail Karmayogi for behavioural
and service-orientation training of frontline staff further contribute to
improving productivity and efficiency. Employees are also encouraged to
undertake online learning through digital platforms such as the iGOT
Karmayogi portal for continuous up-skilling and re-skilling.
In addition, motivational and wellness initiatives, including yoga
sessions, physical fitness activities and stress-management
